UK Non-Dom Regime Abolition 2025: What Replaced It

Last updated: August 2026

The UK non-dom regime abolition took effect on 6 April 2025, ending 200 years of domicile-based taxation and replacing it with a residence-based Foreign Income and Gains (FIG) regime. New UK residents now get 100% tax-free treatment on foreign income and gains, but only for their first four years of residence, and only if they haven't been UK tax resident for a full decade beforehand.

Here's the part most summaries skip: this isn't a smaller version of the old system. It's a different system entirely, built around a hard deadline instead of an indefinite election. If you spent the last few years planning around remittance-basis rules that no longer exist, some of that planning is now obsolete.

We've watched this play out across Atlasway's audience already. Founders and consultants who moved to the UK in 2022 or 2023 assumed they had years of remittance-basis flexibility ahead of them. Many discovered, only after reading the Autumn 2024 Budget documents in detail, that their runway had just been cut to a fixed four-year window with a completely different set of rules.

This guide explains what the old non-dom regime offered, what replaced it, who the new FIG regime actually helps, and what it means if you're now weighing whether the UK is still worth staying in.

Key Takeaways

- The non-dom regime ended on 6 April 2025. UK tax now depends on residence, not domicile, for the first time in over 200 years.

- The new FIG regime gives qualifying new residents 100% UK tax exemption on foreign income and gains for exactly four tax years, with no remittance restriction, then full UK taxation applies.

- Eligibility requires 10 consecutive prior tax years of non-UK residence. Someone who moved to the UK in 2023 doesn't get a fresh four years; they get whatever's left of their original window.

- Inheritance tax moved from a domicile test to a long-term residence test: 10 of the last 20 years of UK residence now triggers worldwide IHT exposure, and that exposure continues for a "tail" period after leaving.

- The Temporary Repatriation Facility offers former remittance-basis users a reduced flat rate to bring pre-2025 offshore funds into the UK, but only for a limited window.

Before the UK non-dom regime abolition: what it used to offer

For over two centuries, the UK taxed residents differently depending on where their "domicile", their permanent legal home, was considered to be. A UK resident whose domicile was legally outside the UK could elect the remittance basis: foreign income and gains stayed outside UK tax entirely, as long as the money never came into the UK.

That election wasn't free forever. After seven of the previous nine tax years as a UK resident, remittance-basis users paid an annual charge, £30,000 initially, rising to £60,000 after 12 years. And after 15 of the previous 20 years of UK residence, a non-dom became deemed domiciled for tax purposes regardless of their legal domicile, at which point the remittance basis stopped being available altogether. HMRC's own guidance on the old rules for non-domiciled residents still lays out how the pre-2025 system worked, useful background if you're untangling historical filings.

The system rewarded people who structured their affairs early and kept foreign wealth genuinely offshore. It also created an entire industry of offshore trusts, remittance planning, and domicile assessments built around indefinite optionality. That optionality is gone now, replaced by a fixed clock that starts the day you become UK tax resident.

UK non-dom regime abolition: what changed on 6 April 2025

HM Treasury's Autumn 2024 Budget policy paper on reforming the taxation of non-UK domiciled individuals confirmed the abolition, and the new rules took effect at the start of the 2025/26 tax year. Domicile stopped being a UK tax concept altogether. Everything that used to hinge on where your father considered his permanent home, or where you intended to eventually retire, now hinges on a much simpler question: how long have you been UK tax resident, or not resident?

Three things changed simultaneously, and it's worth separating them because they affect different people differently:

1. Income and gains taxation moved to the new FIG regime, described below.
2. Inheritance tax moved from domicile to a long-term residence test.
3. Offshore trust protections that shielded settlor-interested trusts from UK tax under the old rules were substantially reduced, though not eliminated for every structure.

Anyone who was mid-way through a remittance-basis claim on 5 April 2025 didn't get to finish out their old terms. The new regime applied from the following day, with transitional provisions, most notably the Temporary Repatriation Facility, covering the gap.

The 4-year FIG regime, explained

The FIG regime is the direct replacement for the remittance basis, and it works on a fundamentally different logic. Instead of an indefinite election available to anyone with foreign domicile, it's a time-limited exemption available to anyone who meets a residence test, regardless of where they were born or where their father was domiciled.

Who qualifies

To claim FIG relief, you need to have been non-UK tax resident for the 10 consecutive tax years immediately before the year you're claiming for. That's the qualifying gate, and it's strict. It doesn't matter whether you were a non-dom under the old rules, a UK domicile who happened to live abroad, or someone who's never set foot in the UK before. Ten clean years of non-residence is the requirement.

One nuance that trips people up: individuals who were already UK resident for fewer than four years as of 6 April 2025 aren't excluded. They can use the FIG regime for whatever years remain of their original four-year window, counted from when their UK residence began, not from 6 April 2025. Someone who arrived in the UK in the 2023/24 tax year has already used one or two years of their allowance before the new regime even started.

What's exempt, and for how long

For each of the four qualifying tax years, 100% of foreign income and gains are exempt from UK tax, and critically, there's no remittance restriction. Under the old rules, bringing offshore money into the UK triggered a tax charge on it. Under FIG, you can bring exempted foreign income and gains into the UK freely during your qualifying years without creating a UK tax liability on that transfer. That's a genuine improvement over the old remittance basis for anyone who actually needs to use their foreign income while living in the UK.

The trade-off is the fixed clock. There's no seven-year grace period, no seniority-based fee structure, no deemed domicile cliff edge to plan around. You get four years, full stop, and then standard UK taxation on worldwide income and gains applies from year five onward, exactly as it would for any other UK tax resident.

How to claim it

FIG relief isn't automatic. It requires an active claim on your Self Assessment return for each year you want to use it, a process HMRC details in its foreign income and gains guidance, and the claim has consequences beyond the exemption itself: claiming FIG relief in a given tax year forfeits your personal allowance and your capital gains tax annual exempt amount for that same year. For most higher earners this trade is straightforward: the FIG exemption is worth far more than the allowances given up. Still, it's a calculation worth actually running rather than assuming.

Mini-story: When Daniela relocated from São Paulo to London in June 2025 to run the European arm of her family's logistics business, she assumed she'd inherited the old non-dom playbook her accountant had described years earlier. She hadn't. Her advisor mapped her prior decade against HMRC's residence test and confirmed she qualified for the full four-year FIG window, having spent all 10 prior years outside the UK.

What surprised her was the claim mechanics. She'd need to file an active election every single year, and in her first year, claiming FIG relief meant giving up roughly £12,570 of personal allowance she'd normally have used against her modest UK salary. Once she ran the numbers against the foreign investment income she was sheltering, it wasn't close. She now reviews the trade-off annually instead of assuming it once and forgetting about it.

Inheritance tax under the new rules

This is the change that gets the least attention relative to its actual financial impact, and it's the one Atlasway sees catch people off guard most often.

Before April 2025, UK inheritance tax on worldwide assets depended on domicile. A non-dom, even one who'd lived in the UK for decades, could often keep foreign assets outside the scope of UK IHT if their legal domicile remained elsewhere.

That's gone. UK IHT now applies to worldwide assets once someone has been UK tax resident for 10 of the last 20 tax years. Cross that threshold, and your entire global estate, property, investments, and business interests held anywhere in the world become exposed to UK inheritance tax at up to 40%.

The part that catches people out is the tail. Long-term residence exposure doesn't end the moment you leave the UK. Once you've triggered the 10-of-20 threshold, IHT exposure continues for a defined period after departure, meaning someone who leaves the UK still needs to plan around UK IHT exposure for years afterward, not just while they're resident.

Note: The long-term residence IHT rules apply regardless of your citizenship or where your assets are physically held. This is a genuinely complex area where estate planning needs to happen well before the 10-year threshold is reached, not after. A qualified UK tax advisor is worth the cost here specifically.

The Temporary Repatriation Facility

For people who built up offshore income and gains under the old remittance basis before 6 April 2025, the government created a bridge: the Temporary Repatriation Facility (TRF). It lets former remittance-basis users bring pre-existing offshore income and gains into the UK at a reduced flat rate, rather than facing full marginal income tax or capital gains tax rates on the transfer.

The TRF is time-limited by design. It exists to clear a specific backlog, funds that were legitimately kept offshore under rules that no longer exist, not to create an ongoing low-tax repatriation channel. If you have meaningful offshore balances accumulated under the old system, this is worth assessing with an advisor before the facility's window closes, since the rate advantage disappears once it does.

Where former non-doms are relocating in 2026

The UK non-dom regime abolition didn't happen in isolation. Several European jurisdictions have spent the last few years actively courting the exact population the UK just lost its edge with, and the outbound movement has been visible enough that it's now a talking point among wealth advisors across the continent.

• Italy's flat-tax regime offers a fixed annual charge, roughly €200,000, on foreign income regardless of amount, an appealing trade for genuinely high earners with substantial foreign income who'd rather pay a predictable flat fee than a percentage.
• Greece's non-dom flat tax works similarly at a lower entry point, around €100,000 annually, aimed at a slightly broader wealth band than Italy's version.
• Cyprus's non-dom regime uses a 60-day physical presence test combined with dividend and interest exemptions, a genuinely different structure from either Italy or Greece.
• Portugal's IFICI (the successor to the old NHR regime) offers targeted benefits for specific professional and research categories, though it's considerably narrower than the old NHR framework it replaced.
• UAE's zero-tax residency remains the most straightforward option for people who don't need EU access and are comfortable relocating fully.

Mini-story: Marcus, a fund manager who'd lived in London since 2015 under the old remittance basis, spent the second half of 2025 running the numbers on staying versus leaving. He'd already used more than 10 of his prior 20 years as a UK resident, which meant the long-term residence IHT test was going to apply to him regardless of what he did next: his worldwide estate was already inside the tail.

That single fact, more than the income tax change itself, is what pushed him to formalize a move to Cyprus in early 2026. He'd assumed the FIG regime discussion was the one that mattered for his decision. It turned out the inheritance tax rules were the deciding factor, not the income exemption he no longer even qualified for.

Is staying in the UK under the FIG regime still worth it?

This is the question Atlasway gets asked most directly, and the honest answer depends heavily on where someone sits relative to the 10-year clocks running underneath both the FIG regime and the IHT threshold.

The FIG regime still works well for:

• New arrivals who've genuinely spent the last 10 years outside the UK and have significant foreign income or gains they want to shelter without remittance restrictions
• People whose UK stay is likely to be four years or fewer, where the exemption window covers most or all of their actual residence
• Founders and consultants relocating to the UK for a specific commercial reason (access to UK banking, a London-based client base, a spouse's career) who need the FIG years to offset the cost of relocating

Staying is a weaker proposition for:

• Anyone approaching or past the 10-of-20-year IHT threshold, since worldwide estate exposure applies regardless of whether income tax treatment is favorable
• People whose foreign income horizon extends well past four years, since standard UK taxation on worldwide income applies from year five with no further transitional relief
• Non-doms who built substantial offshore trust structures under the old protections, since those protections were meaningfully narrowed and the planning that once worked may no longer hold

This doesn't affect:

• UK-domiciled residents who never used the old non-dom regime, since domicile is no longer relevant to their UK tax treatment either way
• Newcomers with modest foreign income who comfortably fit within the FIG exemption regardless of the details, four years of full exemption on a modest foreign income stream is a straightforward win with little downside

Mini-story: Sarah, a Canadian software consultant, moved to Manchester in September 2025 after a decade of remote work across Southeast Asia. Her foreign income, mostly consulting fees from clients in Singapore and Australia, comfortably qualified for the full four-year FIG exemption, and she had no UK-source income complicating the picture. For her, the calculation was clear-cut: claim FIG relief every year, accept the loss of her personal allowance against a UK salary she wasn't drawing anyway, and plan to reassess her situation well before year five arrives. Not every case is this clean, but it illustrates why the same rule change can look like a crisis to one person and a non-event to another.

For readers thinking about offshore reporting obligations that follow you regardless of which regime applies, it's also worth understanding how FATCA and CRS reporting affects global citizens → since those disclosure rules run independently of the FIG regime and apply to most cross-border account holders.

What to do next

The UK non-dom regime abolition replaced a 200-year-old, domicile-based system with a residence-based one built around two hard clocks: four years of FIG exemption for qualifying new residents, and a 10-of-20-year threshold that pulls your worldwide estate into UK inheritance tax regardless of income tax treatment. Both clocks matter more than most summaries suggest, and they don't move at the same pace for everyone.

If you're a new or recent UK arrival, the first step is confirming whether you actually meet the 10-consecutive-year non-residence test, since that single fact determines whether FIG relief is available at all. If you've been in the UK for a decade or more, the inheritance tax tail deserves at least as much attention as the income tax rules, arguably more, since it continues to apply after you've left.

Either way, this is not a set of numbers to self-assess and act on alone. A UK tax advisor who's current on the post-2025 rules can confirm your specific residence history against the FIG and IHT thresholds, and can model the Temporary Repatriation Facility if you're sitting on pre-2025 offshore balances.
